Abstract
A curable composition and a process for using the curable composition within a grating-coupled waveguide (GCW) sensor are disclosed. The composition can be used for facile replication of optical components, specifically those used in a label-independent detection system where operation of the waveguide is dependent on the detailed formation of micro and nano size patterns. The photo or electron beam curable composition has low viscosity (≦500 cPs) and cures to an optically clear material with high glass transition temperature (≧70° C.), low shrinkage on cure, low outgassing, and low extractables.
Claims9
An actinic radiation or electron beam curable composition suitable for use in replicating optical components, comprising:
- a diacrylate monomer mixture comprised of:
- a first diacrylate monomer of the formula:
- wherein
- n=2;
- X is a hydrogen or a methyl group;
- R includes at least one alicyclic ring structure;
- a second diacrylate monomer of a neopentyl glycol propoxylated diacrylate monomer;
- and the composition being substantially free of monofunctional acrylates.
